SNOW- PLOW.

SPEGIFIGATION forming part of Letters Patent No: 244,398, dated July 19, 1881.

Application filed March 15, 1881. (No model.)

and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilledin the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which .form a part of this specification. I

My invention relates to that class of trackclearers in which a beak or mold-board is combined with two rotary disks or wheels inserted in its sides, and provided with blades or paddles for the purpose of cutting into and throwing sidewise the snow. 1

My invention consists in the peculiar construction and arrangement of parts hereinafter described, but more particularly in giving the rotary disks a dished or concave form in crosssection, and in so arranging them that their front edges shall roll together and give a mutual support to one another.

In the accompanying drawings like letters refer to similar parts.

Figure 1 is a perspective view of my com; plete device. Fig. 2 is a sectional view, showin g the arrangement and general construction of itsvcomponent parts; and Fig. 3 is a plan view withportions broken away, exhibitingthe gearing and connections more in detail.

A is the angular or V-shaped beak, preferably formed with a curved front edge, and sweeping backward in a sharp curve. It is designed to be placed in front of the locomotive when used on railroads, or when used on street-car tracks or upon pavements it is to be placed upon a suitably-designed frame-work. Set in each of its two curved sides are the concave disks B B, which reach from the ground to the top of the beak, and the front edges of which form the front edge of the plow-beak at its center. to shafts at their centers 011 the inside, and these shafts revolve in firmly-fixed bearings connected to the frame-work D, which extends forward into the plow and must be made very firm and strong.

The disks B B are firmly attached Upon the inside of the disks are formed, near their centers, the bevel-gears E E, which are driven by means of gears upon the transverse shaft F. The disks are further supported by the friction-rollers g g, placed just inside their edges below and inside the plow.

It will be observed that the arrangement of the disks with reference to each other is such that their front edges rest one against the other. By this arrangement each disk is caused to support and sustain the other at the point of by means of its connection by any proper means with the driving mechanism of the plow. By it and through the gearing previously described the disks B B are rapidly revolved and their front edges saw into and separate, the snow in front, and the flanges O G G strike the snow downward in front, scoop it up and throw it outward and backward to either side.

The edges of the disks B B maybe serrated when used against frozen or crusted snow.

The forms ofthe paddles and the mode of their attachment may also be changed without departing from the spirit of my invention.

I am aware that snow-plows have been provided with revolving disks with flat faces having blades or radial bars thereon, and this I do not claim. My improvement in this regard consists in making the disks of concave form on the outer side. In practice I find that the disks made of the concave form operate in a much more easy and satisfactory manner than those having the fiat blades. The snow passing over the curved or concave surface is more readily removed and has less tendency to become compacted t'han'when used.

I claim- 1. In a snow-plow, the combination of two revolving disks, each constructed of a concave the flat faces are form in cross-section on the outer surface, and provided with a series of paddles or blades upon said surface.

2. In a snow-plow, the combination of two re- 5 volvin g disks, provided with blades, said disks being arranged to roll upon or against each other at the front of the plow, substantially as shown.

3. In a snow-plow, the combination of two 10 upright revolving disks or wheels provided with blades and arranged to run upon and against each other at their forward edges, substantially as shown.

4. In a snow-plow, the combination of a 5 mold-board or plow-point and two revolving disks provided with blades and. seated in opposite sides of the mold-board, the forward edges of said disks extending to or in advance of the front edge of the mold-board, substantially as shown, whereby they are adapted to 20 act directly upon the snow previous to the action of the mold-board thereon.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

LYMAN MORGAN.
